From: Photo Coverage: Come on Babe, They're Gonna Paint the Town - CHICAGO Rehearses for Central Park Concert!

The cast of Chicago, Broadway's longest running musical, is celebrating this production's twentieth birthday today! For this momentous day, the cast are taking to the streets, with a free concert at SummerStage in Central Park. Doors open at 7PM and the show begins at 8PM. We were lucky enough to catch up with some of the cast as they made their final preparations for today's show.
